Electrodeposition coating is a coating method in which conductive paint is electrolyzed by the low-order difference generated by the two electrodes of the anode or cathode, and the paint particles with electric charge move to the object to electrically deposit the coating film on the surface. It is used in places where the product is difficult to paint and has many corners, and is used in automobile parts and home appliances. The color is selected in two types, gray/black.
